The MC44608 is a high performance voltage mode controller
designed for off−line converters. This high voltage circuit that
integrates the start−up current source and the oscillator capacitor,
requires few external components while offering a high flexibility and
reliability.
The device also features a very high efficiency stand−by
management consisting of an effective Pulsed Mode operation. This
technique enables the reduction of the stand−by power consumption to
approximately 1.0 W while delivering 300 mW in a 150 W SMPS. Integrated Start−Up Current Source Lossless Off−Line Start−Up Direct Off−Line Operation Fast Start−Up
